The Castle of St. Peter

Set on a promontory in the harbor of Bodrum, the landmark structure has been witness to six centuries of history. Erected by the Knights Hospitaller in the early 15th century and dedicated to Saint Peter, the castle was built with marble and stones taken from the ruins of the Mausoleum of Halicarnassus.

In the early 16th century the stronghold was captured by the Ottomans and its chapel was converted into a mosque. Today, the impressive sea fort is home to the Museum of Underwater Archaeology.
